Extending Vert.x for Kotlin

Kotlin extensions are developed in this directory.

For instance vertx-core extensions are in the io.vertx.kotlin.core package, etc…​

Extensions needs to be tested and documented.

Bumping Kotlin version

There are a couple of rules to follow before increasing the project versions:

• If changing one between kotlin and kotlinx.coroutines version, make sure that all transitive dependencies, like kotlin-stdlib, still match between the two versions.

• If changing the kotlin version, open a PR also on vertx-codetrans

Kotlin evolves fast, so just change the project versions, test it, and shot a PR.
